I've done some research and there is no easy way to migrate an existing database to SplendidCRM. The problem is that SugarCRM uses varchar(36) for its primary keys and we use uniqueidentifiers. It is possible to convert the IDs to uniqueidentifiers, but all index and keys would need to be dropped before the conversion.
Your best bet is to use the MySQL utilities to dump an XML of the entire database. Then you can import the entire database into SplendidCRM using the Import Database admin tool.
We have made progress automating the migration of SugarCRM to SplendidCRM. We still have a little more work to go, but here are some of the steps we follow:
If you would like to zip your database and sent it to our support staff, they would be happy to work with you on the migration.
